		<h2>代码示例</h2>

		<code>const geometry = new THREE.PlaneGeometry( 1, 1 );
		const material = new THREE.MeshBasicMaterial( {color: 0xffff00, side: THREE.DoubleSide} );
		const plane = new THREE.Mesh( geometry, material );
		scene.add( plane );
		</code>

		<h2>构造器</h2>

		<h3>[name]([param:Float width], [param:Float height], [param:Integer widthSegments], [param:Integer heightSegments])</h3>
		<p>
			width — 平面沿着X轴的宽度。默认值是1。<br />
			height — 平面沿着Y轴的高度。默认值是1。<br />
			widthSegments — （可选）平面的宽度分段数，默认值是1。<br />
			heightSegments — （可选）平面的高度分段数，默认值是1。
		</p>

		<h2>属性</h2>
		<p>共有属性请参见其基类[page:BufferGeometry]。</p>

		<h3>.parameters</h3>
		<p>
			一个包含着构造函数中每个参数的对象。在对象实例化之后，对该属性的任何修改都不会改变这个几何体。
		</p>
